At 5th level, a savage warrior gains a +1 bonus on attack and damage rolls with natural weapons. This bonus also applies to CMB and CMD for grappling. This bonus increases by +1 for every four levels beyond 5th.

At 9th level, when a savage warrior attacks with a natural weapon at the end of a charge, he gains a bonus on his natural weapon attack rolls equal to half his fighter level, while suffering a penalty to his AC equal to half his fighter level. These replace the normal attack roll bonus and AC penalty for charging. This bonus also applies to his CMB for a bull rush or overrun combat maneuvers made when charging.

At 13th level, when using a natural weapon to attack a creature using fire shield or a similar effect that damages creatures attacking it (such as a barbed devil’s barbed defense), a savage warrior reduces the damage from such effects by an amount equal to 1/2 his fighter level.

At 17th level, when using savage charge, the AC penalty is reduced to 1/4 his fighter level instead of 1/2 his fighter level. In addition, a savage warrior can charge through friendly creatures and difficult terrain.
